I would like to change the action bar size. I have tried the following coding.

<style name="MyTheme" parent="@android:style/Theme.Holo.Light">
    <item name="android:actionBarStyle">@style/CustomActionBar</item>
</style>
<style name="CustomActionBar" parent="@android:style/Widget.Holo.Light.ActionBar">
    <!--  <item name="android:background">@drawable/action_bar_style</item> -->
    <item name="android:actionBarSize">15dp</item>
    <item name="android:background">@drawable/header_bar</item>
</style>

But the action bar size didn't change. Is there another way? I am using api level 11.

Thanks.
